FRUIT-CAN FORMING AND SOLDERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 514,453, dated February 13, 1894. Application filed February 23, 1893. Serial No. 463,370. (No model.)

To all whom it may concern:

Be it known that I, EMANUEL EISENBRAUN, of Odessa, Lafayette county, Missouri, have invented certain new and useful Improvements in Fruit-Can Forming and Soldering Machines, of which the following is a full, clear, and exact description, reference being had to theac'companying drawings, forming a part hereof.

My invention relates to machines for forming and spreading the sides of sheet-metal fruit-cans and'more particularly to securing the bottoms and top-rims to the sides of such cans.

The objects of my invention are to produce a can making machine,which shall be simple, strong, durable and inexpensive in construction, and rapid and effective in its operation and which shall be capable of use in making fruit cans more rapidly than heretofore, and which shall, furthermore be easy and rapid to manipulate or operate.

To the above purposes, my invention consists in certain peculiar and novel features of construction and arrangement as hereinafter described and claimed.

In order that my invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in which- Figure l is a perspective view of a can-makin'g machine embodying my invention; the can being shown in position in the machine so as to be operated upon thereby. Fig. 2 is a vertical longitudinal section of the machine on the line 2-2 of Fig. 1. Fig. 3 is a View partly in side elevation and partly in transverse vertical section of the receiving and forming mechanism of the machine. Fig. 4 is a detached perspective view of a portion of the spreading mechanism of the machine. Fig. 5 is an inner end elevation of the adjustable abutting disk of the forming mechanism. Fig. 6 is a detached view in end elevation of certain of the operative parts of the spreading mechanism. Fig. 7 is a detached perspective view of the pivot head of the spreadin g mechanism. Fig. 8 is a horizontal section on the line 8-8 of Fig. 6.

Fig. 9 is a detached perspective view of one of the :S-shaped spring spreader levers of the machine; Fig. 10 is a detached view in side elevation of the retaining bolt for the spreader lever. Fig. 11, is a detail view of one of the adjustable retaining arms of the device.

In the said drawings, let 1 designate a portion of a bench or shelf or other similar sup; port for sustaining the operative mechanism of the machine.

2 designatesa U -shaped clamp bar, one end of which is designed to rest upon the upper side of the support 1, and 3 designates a clamping screw-rodwhich works vertically through the opposite end of the clamp bar 2 and impinges at its upper end against the under side of thesupport 1 so as to retain the clamp in its required position; this screw rod having a suitable head or fingerpiece 4 by which the rod is turned.

5 designates a pair of parallel bars or arms which may be either of wood or metal as preferred and which are also of any suitable or preferred length. Through the rear ends of these bars or arms 5 extends a cross-bolt 6 which also extends transversely through a lug or ear 7 which is formed upon the lower end of the clamp bar 2; the arrangement being such that the bars or arms can be set at any desired angle from the clamp bar 2 and then secured in such position by screwing home the usual retaining nut for the bolt 6.

8 designates a bar which is either of wood or metal and also ofoblong rectangular form and ofanysuitable or preferred length. The rear end 9 of this bar 8 is reduced in width and is interposed between the outer or front ends of the bars or arms just described; the

retaining bolt 10 extending transversely through theouter ends of the bars or arms 5 and also transversely through the reduced inner end of the bar 8 so as to pivotally connect the bar 8 to the bars 5. The outer ends of the arms or bars 5 are preferably beveled obliquely outward and downward, as shown, and the shoulders which are left by reducing the end 9 of the bar 8 are correspondingly in-' clined; the arrangement being such that the I bar 8 shall by the contact of each inclined shoulder with theinclined ends of the bars 5, I

be retained in longitudinal alignment with said bars 5.

23 designates a U-shaped supporting bar, the middle of the lower horizontal portion of which is formed with a pendent tubular pivot 24; thispivot extending downward within a tubular sleeve 25 which is inserted vertically into the outer end of the supporting bar 8 above described. One arm 26 of the U shaped bar 23 is bifurcated or forked at its upper end as at 27 while the opposite arm 28 of the bar 23 is likewise forked or bifurcated at its upper end as at 29. Between the arms or forks 27 is pivoted an abutting disk 30; a transverse pivot pin 31 extending through a projection 32 at the outer side of this disk and-also through the upper ends of the forked arms 27. A spiral contraction spring 33 is connected at its lower ends to the supporting bar 23 near the points of the union of such bar with the arm 26 and the upper end of this spring is connected to a clamp or ring tendsa;suitabledistanne upwardtnward th s I ndardeseetien -of whisk speed Eat the margin Jef said: dis

Through this trunnion ring 40 ex tends a rod or stem 42,the outer end of which extends between the two arms 43 of a fork which is pivoted as at 44 upon'the lower end of the arm 28 at a point near its point of union with the arm 23.. The lower portion of this fork extends horizontally above the bar 23 as shown and through its lower end extends loosely the vertical bolt or rod 22 above referred to, the head of this bolt or rod 22 resting upon the upper side of the arm 43. The inner end of the rod 42 is external-1y screw threaded to enter an internally screwthreaded socket 45 of the disk-shaped head 46, as is clearly shown in Fig. 2. Upon this screwthreaded end of the rod 42 at a point some distance nearer its outer end, is screwed a collar 47 which is also of disk form; the rod 42 ex tending through an internally screw-threaded opening 48 at the center of the collar 47. This collar 47 is also formed with five or any other suitable or preferred number of radial recesses 49 which open at their outer ends at the margin of the collar or disk 47. From each of these recesses 49 extends laterally two sockets 50 which open only at one side of the disk or collar and into the recesses 49 is inserted the inner end of one of five S-shaped spreader-levers 51. The inner end of each of these levers is formed with two oppositely disposed IIO 514,453 r a v 3 positely disposed oppositely'extending studs 53 which are pivotally connected to two oppositely disposed inwardly extending cars 54;

upon each of five spreader plates 55 to be hereinafter more fully explained. The inner ends of these levers 51 are retained within the recesses l9 bya plate 56. This plate corresponding in size and shape to the collar or' head 47 and having a number of radial recesses 57 opening out atth'e margin of the plate and registering with therecesses 49 of the head 47. Upon its inner side the plate 56 isformed with a stud 58 which enters a cavity 59 in the outer side of the head 47; the arrangement being such that the stud 58 prevents the plate 56 from rotating independ ently of the head 47. y

60 designates a companion disk or head to the disk or head 30 above referred to. The rod 42 extends centrally through this head 60 in such manner that the head 60 can freely move longitudinally upon the rod. At its outer side the head 60 is formed centrally with an outwardly extending boss 61 through which the rod 42 also extends and this boss is prolonged outwardly in the form of a sleeve 62 which surrounds the rod 42 and extends outward toward the outer end of the same. The outer end of the sleeve 62 passes loosely through the trunnion-ring 40 and projects outwardly therefrom for a suitable distance, and a spiral expansion spring 64 surrounds the sleeve 62, and bears at its opposite ends against the boss 61 and said trunnion-ring; the tendency of this. spring being to force and hold the clamping heador disk 60to its inward position. A second spiral spring 65 surrounds the outer end portion of the rod 42 and is interposed between the outer end of the sleeve 62 and string 66 which loosely surrounds the rod 42 at the outer portion thereof. This spring 65'serves toforce the ring 66 against the upper ends of the fork 43, for a purpose to be presently explained. Upon its inner side near the outer marginthereof the head 60 carries anumberof adj ustable U shaped supports 67, there being three of such supports shown. Theinner side of the head 60 is formed with three radial grooves 68, the inner ends of which merge into each other and which open at the margin'of the head 60. Each support 67is located within one of these grooves 68 and is adjustable longitudinally therein, and is also secured in any position of longitudinal adjustment by a screw 69 which is inserted into the groove 68 at a point about midway of the length thereof; the head of the screw overlying the arms of the support 67 and the purpose of these supports 67 being hereinafter described. From the inner side of the head 60 projects horizontally a short" tubular portion 70 against the inner side of which rests the outer'sides of the spreader-s 55 above referred toe The spreaders 55, are

of segmental form, in cross-section, as shown, so as to conform to the inner curvature of the can, being formed.

The operation of the above described machine is as follows; when it is desired to form and solder a can, the heads 60-and 30 are first moved upward into inclined position, asshown in Fig. 3. The usual rim to which the top of the can is to be soldered is caused to surround the outer end of the adjustable supporting arms 67. The side portion 80 is now placed around the spreader plates 55, while the bottom of the can is now placed upon the end portion of the can atthe same time bringing the whole can down between the two disks 30 and 60 in parallel position in Fig. 1. The operator now depresses'the treadle'17 pulling down upon the flexible connection 19 and rod 22 and depressing the lower end of the fork 43; the upper ends of said fork 'simultaneously moving inward. 'As the upper spring 65 and forcing the disk 46 inward and extending the levers 51 outward. This causes the spreaders 55 to press outward upon the inner surface of the side of the can so as to cause such to assume a perfectly'cylindrical form to be closely pressed against the outer margins of the bottom and rim of the can. Solder is applied along the longitudinal seam of the side 80. After this has been done, the pressure upon the t'readle 17 is removed,"an'd the spring 65 exerting its pressure against the collar 66, causes the rod or stem to move out ward, and this movement retracts the spread ers, the arms thereof fulcruming against the inner margin of the tubular portion 70 ofthe disk or clamping-head 60. This outward movement of the rod or stem does not affect the position of the clamping-head or disk 60, the spring Get holding said head inward with a yielding pressure. By grasping the can it may now be axially and slowly turnedbetween the clamping-heads or disks while the solder is being applied to secure the bottom rim and head rim to the endsof the can. After this operation is completed, the head is pushed outward and the parts tilted upinto the position shown in Fig. 3; the finished can being removed and the subsequent operations being repetitions of the one just described.

v From the above description, it will be seen that I have produced a can making machine, which is simple, strong, durable, and inexpensive in construction and rapid and efie'ctive in its operation which is easily manipulated and capable of use in the formation of a great variety of fruit cans.
